- Abstract
A comparative analysis of 5 different aluminum cable types tagged J1, J2, J3, J4 and J5, from 5 different cable
manufacturing companies was carried out using 2 different test methods namely- x-ray fluorescence spectrometry
(XRFS) and resistivity test with the main objective of ascertaining why some cables of the same gauge fail under the
same load levels. Purity levels, resistivity and conductivity checks were performed. Equal dimensions of 5 cable brands
were sampled and ground to fine powder. The percentage purity of each sample was determined through XRFS test.
One set of similar samples was subjected to resistivity test. XRFS result shows that J1 had purity of 99.30%, J2,
99.10%, J3, 98.50%, J4, 99.20% and J5, 98.80%. The cable types also had resistivity and conductivity values
respectively as for J1 [2.324x10-9 Ω m & 430.29x106 (Ωm)-1], J2 [3.921x10-9 Ω m & 255.04 x 106 (Ωm)-1], J3 [2.689 x 10-9
Ω m & 371.89 x 106 (Ωm)-1], J4 [2.614x10-9 Ω m & 382.56x106 (Ωm)-1], and J5 [2.890x10-9 Ω m & 346.60 x 106 (Ωm)-1].
Comparing these values to the standard resistivity value of pure aluminum [2.82 x 10-8 Ω m] it would be seen that these
results are in agreement with theoretically computed values. The XRFS test used in this research could be used to test
the purity of aluminum before stretching into cables. It can also be used to determine the standard of aluminum
products. The electrical resistivity test could be used to determine and set a standard resistivity and conductivity
requirements to be met by different cable brands and types used in electric power distribution so as to curb the menace
of cable failure and electric hazards.
